AS,
I don't
I just hope nobody dies while we're giving this moron enough rope.
WW clearly, given that ATC don't monitor 121.5, the first call should be made on the appropriate ATC freq and then, when directed, change to 121.5.
If out in the GAFA down low all/most airline pilots (are supposed) to be monitoring 121.5 so a reasonable chance you'll be heard by someone.
